Bei der Solarthermallyen Energiegewinnung erhitzen Sonnenkollektoren oder Spiegel ein Übertragungsmedium. Es existieren verschiedene Sorten von Solarthermallyen Power stations. Die wichtigsten drei möchten wir hier vorstellen. |

| Tower power station | |
| Many heliostates (mobile, computer-controlled mirrors) surround a tower. The mirrors are aligned sequentially to the sun and reflect the sunlight on the absorber. Inside this device a heat liquid (usually water) is heated up, brought partially to 1000°C, and to evaporation. This steam propels the turbines which are situated in the tower and produce current. |

|
These power stations carry the names as they are used actually only on American farm areas. Special solar collectors focus the sunlight in round mirrors, where the transfer fluid (in these power stations it is oil) is heated up. The heated oil lets water evaporate, which propels again steam turbines. |

| Dish Stirling power stations | |
| Focusing mirrors align themselves after the sun as by the tower power station. |

| The heliostate concentrates the radiation on its focus, in which the Dish Stirling engine is. This engine converts the heat energy directly into mechanical work. |
